WHEEL ATTACHMENT.

combinations of the parts that I shall here? inafter first describe and then point out the novel features, practical operation and idvantages of the device, eventually coneluding with a statement of the novel features and combinations thereof, which I claim to be new.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings in which:

Figure 1 is a side elevation of a'portion of a wheel' equipped with the improvements of my invention; Fic. 2 is a transverse sectional view thereo Fig. 3 isa fragmentary view of a portion of one of the auxiliary rims hereinafter specifically described; and, Fig. 4 is a transverse sectional View thereof.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the saine reference characters.A

Referring to the drawing, the numeral 1 desi ates several of the spokes, 2 the pref:` eraby wooden felly, 3 the metallic channeled rim secured in any desired way to the felly, and 4 the tire of a wheel equipped with the improvements of my invention, all of these parts being of any desired construction, arrangement or design. l

.In carrying out my invention, I have arranged o`n op osite sides pf the tire 4, and spaced somew at therefrom, as best shown in Fi r. 2, two preferably east auxiliary rims 5, said rims being, in properly ap lied position, preferabl on a transverse p ane intersecting the me ian line of the tire and being referably slightly transversely enlarged at intervals as indicated at 6 and formed on their inner face between such enlarged portion with longitudinally extending ribs 7. In the enlarged portion 6 of the auxiliary rims or rings 5, openings 8 are formed. Substantially radially extending do'wels or pins Specification of Letters Patent.

9 proj ect'out-wardlyl through the openings 8, said pins being formed on the outer ends of the brackets 10 thatare arranged in transversely disposed pairs. The brackets 10 preferably curve inwardly toward each other from their outer ends andpreferably contact with the opposite sides of the channeled rim 3 at the base thereof. And the inner ends of the brackets 10 are formed with openings by which they'are adapted to be slipped over Vthe ends of transversely extending bolts 1l, bearing againstthe nuts 12 screwed on the threaded .ends of said-bolts. The bolts 11 pass through the ends of--ciips 13 which partially encircle the spokes-1,".the

nuts 12 securely clamping the clips to 'the i spokes.v At intermediate points in the corresponding brackets 10 openings are formed to receive a tie rod or bolt 14, nuts screwing on the ends of said bolts, and thereby hold.`

ing the corresponding opposite brackets in rigid relation to each other and the wheel.

15 designates tension nuts which screw upon the threaded outer'ends of the brackets 10 and which are adaptedv to ,bear against the inner edges of the auxiliary rims or rings 5 so as to pro erly tension the same after the blocks haveieen put in place.

In the practical application of my improved wheel attachment, the brackets 10 are clamped to the spokes as before set forth and are securely held in proper position by the clips 13 as well as by the tie-rods or bolts 14, it being understood that repara tory to the tightening of the braelets, the

dowels 9 thereof are slipped outwardly through their corresponding openings 8 the auxiliary rims or rings 5. The tension nuts 15 are then worked outwardly on the threaded outer ends of the brackets l0 so as to lace the rings 5 pro erlyunder tension.

Il): is to be understoodp that my' improved wheel attachment is czsigned for a lurality of purposes and possesses severa advantages. For example, the attachment admits of an automobile or the like pulling. itself over orthrough a mud hole in either of .two

ways, for instance by attachin one end of a rope to the rear or power -w eels, and the other end to a stake in advance 'or aheadfofthe automobile in solid ground. As the ep-- -I gine is started'and the rear' wheels slip 'in the mud or sand, the rope will be wound in the groove which is formed between the brackets and the adjacent'iside of the chanv neled rim 3 thereby to all'intents and pur` poses producing a windlass which will draw at their outer ends to the rings and arranged the vehicle ahead. As another application in transversely disposed pairs, clips embracof the device, it is well known, that it someing the spokes of the wheel, bolts holding times happens that the front wheels are on said clips in place and having projecting solid ground while` the rear wheels are in the ends, the brackets being formed at their mud or soft ground and slipping. In such inner ends with openings by which they are an emergency, by windin the rope on the slipped over the projecting ends of the bolts,

front wheels so as to unwind from the botand tie rods extending through correspond,

tom and rear, and securing the loose end to lngly opposite brackets, intermediate the the rear wheel and starting the engine, ends thereof, and arranged to holdthe power is transmitted to the front wheels so brackets against opposite sides of the rim as to draw the vehicle ahead. In addition and .on the ends of the bolts.

to these functions, it is to be noted that the l 2.
